Make each box (not the pages) a separate node with it's own content.
Yes, each box is a node and then the actual page is a page which includes the content of those nodes.
Try checking out the Panels module: http://drupal.org/project/panels
Very interesting. This is actually exactly what I proposed, but it's all setup for me already. :)
OK, I will try with this. It may be easier for me to do this manually, but we will see. :)
Thank you very much!
